🔍 Key Concepts

• Main turbine pre-start procedures and safety interlocks • Purpose and operation of the turning gear (jacking gear) • Why you must avoid mechanical damage when first admitting steam to the turbine

💭 Think About

• Which option, if not done correctly, could cause severe mechanical damage the moment the turbine starts to roll? • Think about what the turning gear is used for during shutdown and lay‑up, and what MUST be its status before admitting steam to the main turbine. • Which choices describe actions that would be unsafe or clearly not done with the unit about to turn on steam power?

✅ Before You Answer

• Identify the normal function of the turning gear and when it should be engaged vs. disengaged. • Eliminate any option that would require opening up major machinery while preparing to get underway (consider safety and oil containment). • Consider which systems (like lube oil and gland sealing steam) are normally kept in service or properly adjusted BEFORE rolling the turbine, not secured or bypassed.
